Hi Kelsey,
I haven't had to do this myself so someone who has done this
before might have a better suggestion.
I wonder if you need to make links from the original device
name to the new device names.
You can see from the zdb -l output below that the device path
is pointing to the original device names (really long device
names).
Thanks,
Cindy

I am in a rather unique situation. I've inherited a zpool composed of
two vdevs. One vdev was roughly 9TB on one RAID 5 array, and the
other vdev is roughly 2TB on a different RAID 5 array. The 9TB
array crashed and was sent to a data recovery firm, and they've given
me a dd image. I've also taken a dd image of the other side.

zpool import identifies that both files are members of the pool, but
there are 'insufficient replicas' and it can not import.
zpool import -d . -F
pool: deep
id: 8026270260630449340
state: UNAVAIL
status: The pool was last accessed by another system.
action: The pool cannot be imported due to damaged devices or data.
see: http://www.sun.com/msg/ZFS-8000-EY
config:
deep UNAVAIL
insufficient replicas
/jbod1-diskbackup/restore/deep_san01_lun.dd UNAVAIL cannot open
/jbod1-diskbackup/restore/deep_Lun0.dd UNAVAIL cannot open
Using zdb, I can see both images have 4 labels. What are my options
in terms of attempting a recovery? I had hoped that ZFS could import
the pool even if the vdevs are now files instead of devices, but
unfortunately it was not so easy.
